Mega-Gengar Ability: Shadow Tag Item: Gengarite - Perish Song - Protect - Hypnosis - Dream Eater Gliscor suffers HARD from Ice type moves, of which are almost always carried by electric and water type pokemon, and its speed isn't the greatest either. To maximize effectiveness, get a Pokémon with Ground and Fighting / Rock / Steel moves, and another pokemon which is a good electric special attacker. Example: Raikou.

As for Mega Gengar, that is a dead gengar  while you try to lay perish song. Instead, run Destiny Bond, Shadow Ball, Sludge Wave, and Will-O-Wisp / Dazzling Gleam / Focus Blast, with a 252 SpAtk 252 Spe 4HP EV spread, and a Modest nature.
